How the estimate is built
Annual sketch = diff% × max(0, payor − recipient). Monthly = annual ÷ 12. Duration sketch uses marriage-year × band factor.
Example scenario
Payor $135,000, recipient $48,000, 40% difference → gap $87,000 → ~$34,800/year (~$2,900/month). Fourteen-year marriage → mid-band duration sketch.
FAQ
Is there a Iowa guideline formula?
Iowa has no single statewide amount formula used here — courts weigh statutory factors (Iowa Code §598.21A). This page is a planning sketch only.
Temporary vs long-term?
This page does not separate temporary orders from long-term awards — map types with your attorney.
Child support first?
Child support affects ability to pay. Model child support separately before locking maintenance.
